SpaceX delivered a fresh crew to the International Space Station on Saturday, making the trip in a quick 15 hours. The four U.S., Russian and Japanese astronauts pulled up in their SpaceX capsule after launching from NASA’s Kennedy Space Center.

Case in point, the aptly-named startup Max Space recently unveiled plans for its private space habitat, dubbed Thunderbird Station, that can expand to a whopping 12,300 cubic feet — roughly a third of the volume of the ISS — while only requiring a single launch of a SpaceX Falcon 9 rocket.
